oLUTH MECHANITSM.

To du whom it may concern..-

Be it lm'own that I, ADAM C. 'HENDRICKav a citizen ofV the UnitedStates, residing at Hagerstown, in the county of Washington and-State ofMaryland, have invented a new and useful Clutch Mechanism, of which thefollowing4 is a specification. i

This invention relates to means for clutching relatively rotating partstogether against relative rotation, and it is applicable to a variety ofstructures-as, for instance, in coup-v ling two rotating parts -or asbrake mechanism to stop the rotation of a part.

. One of the principal objects istoprovide novel mechanism of the abovecharacter which is very simple andineXpensive yet entirely efficient,

- liable to become deranged and, furthermore,

being so constructed that none of said parts is subjected to excessivestrain or wear.

Another and important object is to provide novel brake mechanism wherebyan even and lpowerful stopping action, may be` applied to a wheel orother rotating part, said mechanism being inclosed 'andoccupying verylittle space.

Several embodiments of the invention are I disclosed in th wherein-Figure 1 is a top plan view ofthe improved mechanism when employed as abrake.

.In the embodiment illustrated in the first four figures a tubularcasing 17 is employed,

i stationary being. composed of parts not- Fig.

through which extends a rotatable .driving member, shaft, or axle 18.The casing 17 has its outer end slightly enlarged, as shown at .20, andball-b earings'21 for the shaft are preferably located eing of anysuitable nature. A driven member or wheel 22 is mounted on the end ofthe `shaft 18, and bolted or otherwise secured to the wheel is a sleeve23, having an annular ilange portion 24, surrounding and spacedfrom theenlarged ortion 20 of the casing. For the purpose o braking or stoppinthe wheel 22 the following mechanism is vpre erably employed: Theenlarged portion 20 ofthe casing constitutes a support that is ornonrotatable with respectto the'axle for a rotatable cam element 46',that is located within the enlarged portion 24 of the sleeve 23. Thesaid enlarged portion 20 ofthe casing has an annular outstanding wallthe inner end of the sleeve 47, that closes portion 24 and is providedwith an inwardlyextending stationary guide element v48 in the form of aring that surrounds the cam element 46 and has openings .49therethrough. Rollers 50, located in the openings, have their innersides operating against the cam-sur- 'faces 51 of the cam element 46,while their `outer sides are arranged to bear against a shoe in the formof a split clutch-ring 52, surrounding the guide 48 and secured thereto,as shown at 5.3. This securing means is preferably in the form of a lugriveted to the central portion of the shoe and havinga detachablesliding engagement in an opening 54 in the ring. The shoe is interposedbetween the guide-ring 48 and the sleeve portion 24 and.

is arranged to be spread outwardly against the inner face of said sleeveportion by the clamping-rollers 50 when said clamping-rolls ers aremoved outwardly upon the rotation of the cam element 46. 4This'rotationis ac complished by means of a suitable lever 55, fulcrumed between itsends, as shown at.56, upon\ the wall 47 of the casing Vand havingconnected thereto' a link 57, that is ivoted therein, these bearings rooto a lug 58 on the cam element 46, W 'ch lug l projects through a slot59 in the wall 47. lt will be seen'that if the lever 55 is operated thecam element 46 will be partially revolved and the clam ing-rollers W1llbe moved outwardly, there y spreading the shoe and caus ing it to bebrought 'into binding relation with the surrounding portion of thesleeve. Thus the rotation of the sleeve and the wheel carrying it can becontrolled by the operation suport, and the following mechanism is fssof the lever. lt will be` apparent that this structure is exceedinglysimple and will occupy but a com aratively small space. At the same timet e clutching or braking action is powerful, and said action imparts nolateral strain to the parts, but is evenly distributed entirely aroundthe shaft and casing.

Another embodiment of the invention is disclosed in Figs. 5-8,inclusive. This structure is more particularly intended for `connectinga crank or engine shaft with a transmission-shaft, though notnecessarily limited thereto. The crank or driving shaft is shown at 66and has `keyed or otherwise secured to it a fly-wheel 6l, having on oneside a sleeve or clutch member 62. The support or driven member is inthe form of a shaft 63, having one end vloosely journaled in the hubofthe wheel 6l said shaft having a portion surrounded by the sleeve .62.Se-

`curedvto the shaft 63 within the sleeve 62-is a hub 64, having anoutstanding wall 65,

provided with an annular guide element in the form of a ring 66, that isthus `fixed to the shaft 63. The ring 66 is provided with open-I ings 67therethrough. ldotatably mounted on the hub 64 and located within theguidering 66 is a cam 'member 68,\provided with cam-surfaces 69,arranged' inside rthe openings 67. Rollers 76, operated by thecamsurfaces, are located in the openings 67 and` are arranged tonbearagainst a split shoe 7 1,',

surrounding the ring 66 and secured thereto, asshown at 72. The shoe isarranged to be moved into and out oi engagement with the inner face ofthe sleeve ,62 by the clampingrollers 70 when said rollers are operatedby the cam element, To Vsecure these various movements, it thereforebecomes necessary to effect the movement of the cam upon 'its .preera-bly,provided` The cam element has acollar 73.. projecting outwardlybeyond the guide-ring and having inclined slots 74 there- 1n... Aguide75, suitably secured to the shaft 63, is provided with an angular outerface 76, on which is slidably mounted an actuating-sleeve` 77. Thissleeve has its inner end movable longitudinally withinthecollar 73 l andprovided with outstanding lugs` 7 8 that engage' inthe slots 74C, Thesleeve 7 7 fur'- thermore, 'has an annular oove 78a to receive theordinary yoke o a shifting-lever.

. A s ring 79, surrounding the outer portion the parts o ,with thesleeve 62.

esaoaa lugs 78, riding in the inclined slots, will cause Aa partial roation of the cam element, thereby moving the claniping-rollers outwardlyand causing the shoe to be s read apart and to be brought into clutchingengagement The result is that `the shaft 63 will be clutched to theshaft 60, an thetwo will rotate together.- 1

An extension or modiiicatiouof this latter embodiment is disclosedin'F-igs. 9-12, inclusive. This structure is clearly applicable forreversing or differential speed gearing. The supporting member in thepresent case is the driving4 member, and is in the form of a shaft 6l,while the driven members are pulleys or gears 82, loosely journaled onthe shaft 8i and spaced apart, their longitudinal outward movements uponthe shaft being prohibited by suitable collars 63.y These driven membersare lprovided on their innerv sides with clutch-sleeve ortions Se, andkeyed to the shaft within the sleeve portions 84 are hubs 85, havingoutstanding walls 86, lprovided with annular guide' elements in the formof rings 87. Cam elements 86 are jeurnaled on the hubsy 85 within therings 87 and have collars 89 provided with slots 90, having `inclinedportions. Clutch-shoes 9i are secured to the guide-rings 87 and areinterposed between the same and the sleeve portionsd, being movable intoand out of coaction with the same. Rollers 92, operated upon bythe camelementsand located in therings, effect the .movement of the shoes.

`tirraiiged between the hubs 85 and suitably secured to the shaft Sluisa ide 93, having an. angular outer face, and s idably mounted on thisguide is an actuating-sleeve 9,4, having an intermediate annular groove95 for vthe yoke of an ordinary controlling-lever.

The opposite ends of the sleeve 94 are rovided with outstanding lugs 96,which ugs respectively engage in theslots 90 of the canielement collars89., With this 'arrangement when the actuatingf'sleeve-Qa'isin itscentral position and the lugs 916 are at the outer ends i of thelinclined portions of the slots both the driven members will-'beunclutched and the.

shaft 8l can rotate vindependently thereof. lf the'actuating-sleeve 941s movedin one direction,`it will cause a partial rotation of one of thecam elements with respect to the shaft, thereby moving the rollers thatcoperate with said cam element outwardly and' causing the shoe to clutchthe driven member. The other member will not be affected by thismovement. ment takes place, the member above described will beunclutched bythe retrograde movement of the cam element, While thelatterv .memberI will be clutched to the shaft. Thus a simple reversingor differential speed ear is provided, and from the above it will eevident that the invention is ca able of a wide range of application andusefu ness.
